I won't spoil anything, but I will tell you a rough outline of the movie. Empire of the Sun is set in the British part of Shanghai in the 1930s. The story revolves around a young English boy named Jamie. He is a spoilt brat from a rich family to begin with. His life would completely change however, when the armies of Imperial Japan invade Shanghai, resulting in this little boys life radically changing as he is separated from his wealthy, protective parents in all the chaos and confusion and thus must struggle to survive. This movie is based on a true story and does a good job at illustrating how life became difficult for the British and Chinese alike, and even the Japanese as their defeat at the atom bombs drew nearer and nearer. In a way, this movie taught me to be compassionate to all people, whether they are wealthy or poor and regardless or their ethnic background. This is because we are all humans with the same emotions and are vulnerable to suffering. (I feel I should mention that ethnicity has no place in the study of Zen/Chan/meditative path to enlightenment. Ethnicity only exists in the phenomenal realm which may also be known as the realm of perceived reality. This is an artificial place that creates politics that can result in war, a terrible by product in this realm.)
Empire of the Sun is a movie that I highly recommend. I have not been able to find the full movie online for free. I did find the trailer however. Take a look and see if it's a film that you might like to track down and see.
